The O-phosphoserine produced by such an organism can then be reacted with a sulfide in the presence of a sulfydrylase or a microorganism expressing a sulfhydrylase to produce cysteine or a derivative thereof. Microorganisms having the properties noted above are also provided herein. | 07-26-2012 |
20120190083 | MICROORGANISM PRODUCING O-PHOSPHOSERINE AND METHOD OF PRODUCING L-CYSTEINE OR DERIVATIVES THEREOF FROM O-PHOSPHOSERINE USING THE SAME - The present invention provides methods for the production of cysteine or derivates thereof by culturing a microorganism having reduced activity of endogenous phosphoserine phosphatase and the activity of PhnC, PhnD, and PhnE is reduced, and enhanced activity of phosphoglycerate dehydrogenase and/or phosphoserine aminotransferase. The O-phosphoserine produced by such an organism can then be reacted with a sulfide in the presence of a sulfydrylase or a microorganism expressing a sulfhydrylase to produce cysteine or a derivative thereof. Microorganisms having these reduced and enhanced properties noted above are also provided herein. | 07-26-2012 |
20130231503 | Microorganism producing L-methionine precursor and method of producing L-methionine and organic acid from the L-methionine precursor - The present invention relates to a method for producing L-methionine, comprising: i) culturing an L-methionine precursor-producing microorganism strain in a fermentation solution, so that the L-methionine precursor accumulates in the solution; and ii) mixing a converting enzyme and methylmercaptan or its salts with at least a portion of the solution to convert the accumulated L-methionine precursor into L-methionine, as well as to microorganism strains used in each step. | 09-05-2013 |

20140296466 | Method for Producing Bio-Based Homoserine Lactone and Bio-Based Organic Acid from O-Acyl Homoserine Produced by Microorganisms - The present invention relates to a method of producing bio-based homoserine lactone and bio-based organic acid through hydrolysis of O-acyl homoserine produced by a microorganism in the presence of an acid catalyst. According to the present invention, O-acyl homoserine produced by a microorganism is used as a raw material for producing 1,4-butanediol, gamma-butyrolactone, tetrahydrofuran and the like, which are industrially highly useful. The O-acyl homoserine produced by a microorganism can substitute conventional petrochemical products, can solve environmental concerns, including the emission of pollutants and the exhaustion of natural resources, and can be continuously renewable so as not to exhaust natural resources. | 10-02-2014 |
